Army of Mississippi

The Army of Mississippi, also known as the Army of the West, was an army of the Confederate States Army that existed from March 1862 to June 1864 during the American Civil War. Albert Sidney Johnston commanded the army at the Battle of Shiloh in April 1862, in which the army suffered heavy losses and Johnston was killed. John C. Pemberton led the army in the defense of Vicksburg, Mississippi in 1863, and much of the army was forced to surrender in the battle. The army was recreated as III Corps of the Army of Tennessee under William J. Hardee in July 1863, and it existed until June 1864.
